Calculate the empirical formula for each of the following natural flavors based on their elemental mass percent composition.
tamaranim1 [39]

Answer:

Nitroglycerin- CNH2O3

Vanilin- C3H3O

Explanation:

The empirical formula is the simplest formula of a compound. It depicts the ratio of atoms of each element in the compound. It can be obtained by dividing the percentage by mass of each element by its relative atomic mass. The lowest ratio obtained is now used to divide all the previously obtained ratios and whole number values are recorded. This shows the ratio of atoms of each element present, hence the empirical formula.

Which of the following occurs when a reaction in a solution is at equilibrium and more product is added to the solution?No chang
LenaWriter [7]

Answer:

Equilibrium shifts to produce more reactant

Explanation:

  • <em>Le Châtelier's principle</em> <em>states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.</em>

  • When more product is added to the solution:

<em>This will increase the concentration of the products side, so the reaction will be shifted to the lift side (reactants side) to suppress the increase in the concentration of Products.</em>

<em />

<em>So, the right choice is: Equilibrium shifts to produce more reactant</em>
